4 CONFIGURATION

Note: The status of the I/O can be monitored in Cscape Software.

4.1 Software Configuration

Preliminary configuration procedures that apply to SmartStack™ Modules are contained in the hardware

manual of the controller you are using. Refer to the Additional References section in this data sheet for

a listing of hardware manuals.

I/O Map Tab

The I/O Map describes which I/O registers are assigned to a specific SmartStack™ Module and where the
module is located in the point map. The I/O Map is determined by the model number and location within
the SmartStack™. The I/O Map is not

a) Input range for each channel may be selected independently.
b) Filter Constant sets the level of digital filtering according to the following chart.
c) In addition to configuring the module setup, the hardware must be jumpered to select the

appropriate range for each channel.

Digital Filtering: The illustration above demonstrates the effect of digital filtering (set with Filter Constant)

on module response to a temperature change.

4.2 Hardware Configuration

The inputs are referenced to the bus common. Each of the inputs can be jumper-selected for one of the
three input types. Behind each of the input pins is a corresponding group of four jumper pins with a
programming plug.

a) To select 5V input: Connect the two pins nearest the connector.
b) To select thermistor input: Connect the two pins nearest input 1.
c) To select 20mA input: Connect the two pins nearest input 12.

Note: It is also necessary to specify the input channel type in Cscape along with the

temperature format.

5 INPUT CONVERSION FACTOR

The following table describes how real-world inputs are scaled into the controller. Given a known input
voltage, the data value is configured by using the conversion factor from the table. The following formula
is used:

Data = Voltage In (Vin) / Conversion Factor

Example: The user selects avoltage range of 0 to +5 VDC:

1) The known input voltage is 3 VDC.

2) Using the table, the conversion factor for the voltage range of 0 to +5 VDC is 0.00015625.

3) To determine the data value, the formula is used:
Data = Vin / Conversion Factor
19200 = 3 VDC / 0.00015625

6 INSTALLATION / SAFETY

Warning: Remove power from the OCS controller, CAN port, and any peripheral equipment

connected to this local system before adding or replacing this or any module.

a) All applicable codes and standards should be followed in the installation of this product.
b) Shielded, twisted-pair wiring should be used for best performance.
c) Shields should be tied directly to the ground block within the panel.
d) Use the following wire type or equivalent:

Belden 8441

For detailed installation and a handy checklist
clearances, refer to the hardware manual of the controller you are using. (See the Additional References
section in this document.).

When found on the product, the following symbols specify:

that covers panel box layout requirements and minimum

Warning: Consult user documentation.

Warning: Electrical Shock Hazard.

WARNING: To avoid the risk of electric shock or burns, always connect the safety (or earth)

ground before making any other connections.

WARNING: To reduce the risk of fire, electrical shock, or physical injury it is strongly

recommended to fuse the voltage measurement inputs. Be sure to locate fuses as close to the
source as possible.

WARNING: Replace fuse with the same type and rating to provide protection against risk of fire

and shock hazards.

WARNING: In the event of repeated failure, do not replace the fuse again as a repeated failure

indicates a defective condition that will not clear by replacing the fuse.

WARNING: Only qualified electrical personnel familiar with the construction and operation of

this equipment and the hazards involved should install, adjust, operate, or service this
equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or loss
of life.

For detailed installation and a handy checklist

that covers panel box layout requirements and minimum
clearances, refer to the hardware manual of the controller you are using. (See the Additional References
section in this document.):

• All applicable codes and standards need to be followed in the installation of this product.

• For I/O wiring (discrete), use the following wire type or equivalent: Belden 9918, 18 AWG or

larger.

Adhere to the following safety precautions whenever any type of connection is made to the module.

• Connect the green safety (earth) ground first before making any other connections.

• When connecting to electric circuits or pulse-initiating equipment, open their related breakers.

make connections to live power lines.

Do not

• Make connections to the module first; then connect to the circuit to be monitored.

• Route power wires in a safe manner in accordance with good practice and local codes.

• Wear proper personal protective equipment including safety glasses and insulated gloves

when making connections to power circuits.

• Ensure hands, shoes, and floor are dry before making any connection to a power line.

• Make sure the unit is turned OFF before making connection to terminals. Make sure all

circuits are de-energized before making connections.

• Before each use, inspect all cables for breaks or cracks in the insulation. Replace
immediately if defective.
